ROCKING-CHAIR CHURNlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 233,500, dated October 19, 1880.

Application filed May 3, 1880. (No model.)

T 0 all whom it may concern:

Be it known that I, EDsoN M. GASKILL, of Edenton, Glermont county, State of Ohio, have invented a new and useful Improvement in Rocking-Chair Ohurning-lvlachines, of which the following is a specification.

Figure l is aperspectiveview of the improvement. Fig. 2 is a side elevation, partly in section. Fig. 3 is a vertical cross-section of the rack-bar, gear-wheel, and hinged arm, and Fig. 4 is a plan View of the gear-wheel.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish a churning-machine so constructed that it will be operated by giving oscillating movements to the chair upon which the operator sits.

The invention consists in constructing a ch urning-machine of a chair, a con necting-rod, a pivoted upright, a rack-bar, a gear-wheel, a hinged arm having keeper and hand-screw, and a treadle, so that the churn-dasher can be operated by the oscillation of the chair, as will be hereinafter fully described.

A represents a chair, the rear legs of which are set in sockets or recesses formed in the floor or in blocks or plates attached to the floor.

To the lower part of a forward leg of the chairAis pivoted thelower end of an inclined connecting-bar, B, the upper end of which is pivoted to an upright bar, G. The lower end of the bar 0 is pivoted to the tioor, or to a support attached to the floor.

To the upper part of the upright bar 0 is pivoted the rear end of a bar, D, upon the inner side of the forward part of which are formed rack-teeth to en gage with the teeth of the gearwheel E, attached to the upper part of the handle F of the dasher G.

The dasher G is formed of three (more or less) wings attached longitudinally to the ban dle F, and having longitudinal slots formed in their inner parts.

The lower end of the dasher-handle F revolves in a socket or step, H, attached to the bottom of the churn I. The upper end of the dasher-handle F revolves in a socket in the lower side of the forward end of the arm J, the rear end of which is hinged to the upper end of a standard, K, attached to the floor or to some other suitable support.

The hinged arm J is held from dropping below a horizontal position by a brace, L, rigidly attached to it, and which rests against the forward side of the upper part of the standard K. The standard K is strengthened in position by a brace, M, attached to its upper part, and the lower end of which is attached to the floor.

To the pivoted upright O is pivoted the end of the arm N, the other end of which is attached to or formed upon the bar 0, which is bent into crank form, and is hinged at its ends to the floor, so that the arm N and crank-bar O may form a treadle or foot-lever to assistin working the machine.

To the forward end of the hinged arm J is attached the end of a metal strap, P, which is bent downward and inward to form a keeper to keep the rack-barD in place. Thelower or free end of the strap 1? projects inward far enough to pass beneath the gear-wheel E and prevent it from slipping down too far upon the dasher-handle F.

The rack-bar D is held against the gearwheel E by a hand-screw, Q3, which passes in through the outer part of the strap or keeper P, so that its forward end may rest against the outer side of the said rack-bar D.

In using the machine the operator sits in the chair A, takes hold of the pivoted upright O with one hand, and places his feet upon the treadle 0 N. The operator then tilts the chair A back, and at the same time presses against the upright O and treadle N O with his feet and hand. As the operator ceases to press against the upright O and treadle N 0 his weight brings the chair A back to its former position. These movements give a reciprocating movement to the rack-bar D, and through it to the churn-dasher G, bringing the butter in a very short time. By oscillating the chair A very slightly a slight reciprocating movement will be given to the dasher G, which will gather the butter very quickly and very thoroughly into a compact mass. The butter may then be removed from the churn in the usual way.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent-- 1. A ch urnin g-machine constructed substantially as herein shown and described, whereby the churn-dasher will be operated by the 0scillation of the chair, as set forth.

3. In a churning-machine, the combination, with the pivoted upright C, that carries the rack-bar D, of the treadle O N, substantially as herein shown and described, whereby the operator may use his feet to assist in operatin g the chnrn-dasher, as set forth.

4. In a churning-machine, the combination, with the rack-bar D and the hinged arm J, of the strap or keeper P and the hand-screw Q, substantially as herein shown and described, whereby the rack-bar is kept in place and in gear with the gear-wheel E, attached to the dasher-handle F, as set forth.
